Can I sue a company for discrimination for offering a man $2 more than me, even if i didnt take the job?

I was offered a job for $12 an hour as a team lead. A man that I met at my current job told me he was offered $14 for the same position but turned it down because of being offered more at the current company. Can I take them to court for discrimination for offering him more than me? I was offered another interview but tookmy current job before the interview. After he told me how much he was offered I sent them another email asking if they would pay me $14 an hour and they never replied. Before I met that kid, I had sent the company an email asking for $15 and they told me that was out of their range. What do you think I should do?
